Abstract

In our study, some newly synthesized aryl-substituted pyrazole derivatives mimicking cis-diphenylethylene scaffold of two apoptotic inducing agents celecoxib and combretastatin A-4 were found to have strong antiproliferative as well as antiinflammatory activities. Among these coxib–combretastatin hybrids, two lead compounds 8 and 6c simultaneously inhibited prostaglandin E2 (PGE2) production in LPS-activated murine macrophage RAW 264.7 cells and suppressed cell cycle progression of MCF7 cells at G2/M or G0/G1 phases, but only compound 8 induced apoptosis via caspase-3 activation. Both the lead compounds showed good docking energies with both protein targets COX-2 and tubulin in the molecule interaction modeling. The cis-diphenylethylene scaffold of celecoxib or combretastatin A-4 as well as functional groups such as the ethyl ester group and the sulfonamide could be considered as potential key features for the dual activity of studied compounds meanwhile the trimethoxybenzene remained the crucial characterization of the newly derived compounds of combretastatins.
